Description

本発明は、居室内に設置され、直接風による体感温度の減少や室内の空気の循環に使用される送風機に関するものである。 The present invention is installed in the room, to a blower that is used to circulate the air in the reduction or room sensible temperature by direct wind.

従来、この種の送風機は、羽根車とモータを台座となる基部に内包して、基部上部に備えられた円環形状の送風部から床面と水平方向に吹出すようにて空気の循環及び空気の流れを生じさせる家庭用送風機が知られている。 Conventionally, this kind of blower, the enclosing impeller and motor to the base serving as a base, the circulation of air at blown out from the blowing unit of annular shape provided in the base top to the floor and horizontal and household blower to produce a flow of air is known. (例えば、特許文献1参照)。 (E.g., see Patent Document 1).

以下、その送風機について図17および図18を参照しながら説明する。 It will be described below with reference to FIGS. 17 and 18 for the blower.

図17は、送風機組立体100をその正面から見た状態で示している。 Figure 17 shows a state viewed fan assembly 100 from the front. 送風機組立体100は、中央開口部102を画定している環状ノズル101を有している。 Fan assembly 100 has an annular nozzle 101 defining a central opening 102. 図18も参照すると、環状ノズル101は、内部通路110、口112及び口112に隣接して位置するコアンダ面114を有している。 When Figure 18 is also referenced, annular nozzle 101 includes a Coanda surface 114 positioned adjacent to the internal passage 110, the mouth 112 and the mouth 112. 環状ノズル101は、外側ケーシング118を備えた基部116に連結されると共にこれによって支持されている。 Annular nozzle 101, thereby being supported while being connected to the base 116 with an outer casing 118. 環状ノズル101を通る空気流を生じさせるモータ122がモータハウジング126と共に基部116の内部に配置されている。 Motor 122 for creating an air flow through the annular nozzle 101 is arranged inside the base portion 116 together with the motor housing 126. さらに、インペラ(羽根車)130が、モータ122から外方に延びる回転シャフトに連結され、ディフューザ132が、インペラ130の下流側に位置決めされている。 Further, an impeller (impeller) 130 connected to a rotary shaft extending from the motor 122 to the outside, the diffuser 132 is positioned downstream of the impeller 130. インペラ130の入口134が、基部116の外側ケーシング118に形成された空気入口124と連通している。 Inlet 134 of the impeller 130 is in communication with the air inlet 124 formed on the outer casing 118 of the base 116. ディフューザ132の出口136及びインペラ130排気部は、インペラ130から環状ノズル101の内部通路110への空気流を確立するために、基部116の内部に配置された中空通路部分及びダクトと連通している。 Outlet 136 and the impeller 130 exhaust portion of the diffuser 132, in order from the impeller 130 to establish a flow of air into the interior passage 110 of the annular nozzle 101, and communicates with the hollow passage portion and duct disposed in the interior of the base 116 . モータ122は、電気接続部及び電源に接続され、複数個の選択ボタン120により、ユーザは、送風機組立体100を操作することができる。 Motor 122 is connected to the electrical connections and the power supply, the plurality of selection buttons 120, the user can operate the fan assembly 100.

上記構成において、上述した送風機組立体100は、以下のように動作する。 In the above structure, the fan assembly 100 described above operates as follows. ユーザが複数個の選択ボタン120の中から適当に選択してモータ122が駆動される。 User motor 122 by suitably selecting from among a plurality of selection buttons 120 are driven. かくして、モータ122が起動され、空気が空気入口124を介して送風機組立体100内に吸い込まれる。 Thus, the motor 122 is activated, air is drawn into the fan assembly 100 via the air inlet 124. 空気は、外側ケーシング118を通り、インペラ130の入口134まで流れる。 Air passes through the outer casing 118, it flows to the inlet 134 of the impeller 130. ディフューザ132の出口136及びインペラ130の排気部を出た空気流は、内部通路110を通って互いに逆の方向に進む2つの空気流に分けられる。 Airflow exiting the exhaust section of the outlet 136 and the impeller 130 of the diffuser 132 is divided into two air streams proceeding opposite directions through the interior passage 110. 空気流は、これが口112に入る際に絞られ、そして口112の出口144のところで更に絞られる。 Air flow, which is narrowed down as it enters the mouth 112, and is further narrowed at the outlet 144 of the mouth 112. この絞りにより、システム中に圧力が生じる。 This diaphragm, a pressure occurs in the system. このように作られた空気流は、絞りにより生じる圧力に打ち勝ち、空気流は、一次空気流として出口144を通って出る。 Thus produced air stream, overcomes the pressure created by the diaphragm, the air stream exits through the outlet 144 as primary air flow. 一次空気流は、ガイド部分148の配置により、ユーザに向かって集中し又は集束して向けられる。 The primary air flow, the arrangement of the guide portion 148 is directed to concentrated or focused towards the user. 二次空気流は、外部環境、特に出口144周りの領域及び環状ノズル101の外縁部周りからの空気の同伴によって生じる。 The secondary air flow is caused by the external environment, particularly the air from around the outer edge of the region and the annular nozzle 101 around outlet 144 entrained. この二次空気流は、中央開口部102を通り、ここで、一次空気流と混ざり合って送風機組立体100から前方に放出される全空気流が生じる。 This secondary air flow passes through the central opening 102, wherein the total air flow is generated which is released from the primary air flow and mixed each other in fan assembly 100 forward.

本発明の請求項1記載の天井扇は、箱体に空気を取り入れる吸込み口と、高圧空気を発生するための羽根車と前記羽根車を駆動するためのモータで構成された高圧空気発生手段とが設けられた高圧空気発生部と、高圧空気を気流として吹出すための吹出し口を有する環形状の気流吹出し部を備えた送風機であって、前記気流吹出し部を環形状に対して内外方向に平行となるよう2重に備え、各気流吹出し部は内部を空気が流れる連通部を介して前記高圧空気発生部に保持され、各吹出し口は前記気流吹出し部の環形状に対してほぼ垂直方向に開口し、内側の気流吹出し部が外向に傾き、外側の気流吹出し部が内向きに傾き、各吹出し部の風量を変更することで、環形状に対して内外方向の送風角度を変更できることを特徴とする送風機である Ceiling fan according to claim 1 of the present invention, the inlet taking in air into the box, and a high pressure air generating means constituted by the motor for driving the impeller and the impeller for generating a high-pressure air a high pressure air generator which is provided, a high-pressure air to a blower having a blowing airflow portion of annular shape having the outlet for blowing the air flow, the air flow blowing portion inward and outward relative to the ring-shaped with a double so as to be parallel, each blowing airflow portion is held inside the high pressure air generator via a communicating portion through which the air flows, each air outlet is substantially perpendicular direction to the annular shape of the air flow blowing unit open to, blowing airflow of the inner is inclined in the outward slope on the outside of the blowing airflow portion is inwardly by changing the air volume of the balloon portion, that can change the air blowing angles of the inner and outer direction with respect to the ring-shaped It is a blower which is characterized

これにより、各気流吹出し部の気流方向に加えて、両気流吹出しに同等風量を供給することで、各気流吹出し部の気流が衝突して合成されて、中間方向の気流を発生することができ、この風量調整を選択的に行うことで気流方向が変更できる。 Thus, in addition to the air flow direction of the blowing airflow portion, by supplying the same air volume to blow both airflow, is synthesized airflow of each blowing airflow portions collide, it is possible to generate an intermediate direction of the air flow You can change airflow direction by performing the air quantity adjusting selectively.

また、気流吹出し部が同心の円環形状であることを特徴とするものであり、円環部中心を軸として吹出し部が軸対称形状となるので、円環に対して周方向に一様な風を送ることができ、周方向に強風、弱風のムラの無い快適な気流を生成することができる。 It is intended, wherein the blowing airflow portion is concentric annular shape, because part balloon as an axis the annular portion center is axisymmetric, uniform in the circumferential direction with respect to the circular ring it is possible to send the wind, strong wind in the circumferential direction, it is possible to generate a no comfortable stream of non-uniformity of the weak wind.

また、吹出し部の環形状の全周にわたって環形状に対して軸方向気流とした通常送風と、全周にわたって軸方向に対して内側に傾いた内向き気流としたスポット送風と、全周にわたって軸方向に対して外側に傾いた外向き気流としたワイド送風と、を切替可能としたことを特徴とするものであり、全周の気流を送風機直下の内側に集中して強い涼風を受ける場合と、全周の気流を外側に向けて広範囲で涼風を受ける場合の選択が可能となり、状況に応じた気流を生成することが出来る。 Further, usually a blowing that axial air flow relative to the ring shape over the entire circumference of the balloon portion of the ring shape, and spot blast was inward airflow inclined inwardly relative to the axial direction over the entire circumference, the axis over the entire circumference and characterized in that it has a wide blast was outward airflow inclined outwardly, and can be switched to the direction, and if subjected to strong cool breeze to concentrate the entire circumference of the air flow inside immediately below the blower enables selection when receiving a cool breeze in a wide range towards the entire circumference of the air flow to the outside, it is possible to generate an air flow according to the situation.

また、吹出し部を環形状の周方向に等しい幅で偶数分割となるように分割し、任意箇所の吹出し部を外向き送風部とし、前記外向き送風部から最遠方となって向かい合う吹出し口を内向き送風部として、任意箇所の送風部を切り替えることで風向変化を可能としたものであり、2つの向かい合う送風部で一方が内向き送風であり、もう一方が外向き送風とすると、環形状の外側に向かう方向は同一方向となり、任意方向にスポット的に送風できるので全周方向への気流が必要なく所望の送風方向に対してのみ気流が必要な場合に効率的に気流を生成することができる。 Also, the balloon portion of the ring shape dividing so that an even split in the circumferential direction equal width, a blowing portion of any location and outward blower, the outward farthest and turned to face air outlet from the blower unit as inward blowing part, which made it possible to wind direction change by switching the blower of any position, one in two opposite blower is inwardly blown, the other is to outward air blowing, ring shape it is toward the outside becomes the same direction, to generate efficiently airflow when the airflow is required only for the desired blowing direction airflow without the need for the entire circumferential direction because it spot to blow in an arbitrary direction can.

また、2つの気流吹出し部が内外方向に接するものであり、吹出し口では高速気流を発生させるために狭小隙間となり、気流吹き出し部形状はこの吹出し口形状だけを形成すればよいので、内外方向に薄型の形状となり易い。 It is intended two blowing airflow portion is in contact with the inner and outer direction, becomes narrow gap in order to generate the high-speed air stream in the air outlet, because the blowing airflow section shape may be only formed this air outlet shape, the inner and outer direction It tends to be a thin shape. しかし薄型のために強度が不足するのを防ぐため、2つの気流吹き出し部を接して構成することで、強度を向上することが可能となる。 However in order to prevent the strength for thin that insufficient, by configuring in contact with two blowing airflow portion, it is possible to improve the strength.

また、各吹出し部への風量を高圧空気発生部内の風量可変機構にて調整するものであり、高圧空気発生部内に収まる風量変更機構を備えることで、スリット状に長くなる気流吹出し部に大きな可変フィンを備えて送風角度を変更するよりも、小型で容易な構成とすることができる。 Further, the air volume of each balloon unit is intended to adjust at flow rate adjustment mechanism in the high-pressure air generator, by providing the air amount change mechanism that fits to the high-pressure air generation portion, great variability in the blowing airflow portion made long slit-like Rather than changing the blowing angle comprises a fin may be a compact and simple configuration.

また、高圧空気発生部が吹出し部の環形状内側にあり、かつダンパが環形状に対して周方向にスライドする円管形状であって、円管曲面部に空けられた穴と連通部に通じる穴との重なり量を変えることで各吹出し部への風量を変更できるものであり、高圧空気発生部が吹出し部の内部にある場合は、1つの吹出し部に対して環形状に対して周方向の複数の連通部で吹出し部を保持するのが望ましい。 Further, there is a ring shape inside of the high pressure air generator is blowing unit, and the damper is a circular tube shape that slides in the circumferential direction with respect to the ring shape, leading to the hole and communicating portion bored in a circular tube curved portion are those that can change the volume of air to each balloon unit by changing the amount of overlap between the holes, if internal high pressure air generator is blowing portion, the circumferential direction relative to the ring shape with respect to one blowing unit of it it may be desirable to retain blowing portion in a plurality of communication portions. ここで、高圧空気発生部のためにダンパ前後の圧力差が大きいので、一辺がヒンジ等で固定された開閉式のダンパでは圧力によって開閉に余分な大きな力を要し、環形状に対して垂直にスライドするダンパでは、複数の連通部の風量を一度に変化させるとよいが、リング状のダンパでは、作用から離れた箇所の摩擦が大きくなり無駄な力が必要となるが、周方向のスライドにおいては摩擦が大きくならず無駄な力が必要とならないので1つのアクチュエータで容易にダンパを開閉できる構造とできる。 Here, the pressure differential across the damper for the high pressure air generator is large, a side requires an extra large force to the opening and closing by the pressure at a fixed opening and closing dampers in the hinge or the like, perpendicular to the ring-shaped in the sliding damper, air volume of the plurality of communication portions a may be changed at a time, in the ring-shaped damper, it is necessary wasteful force increases the friction distant locations from the action, the circumferential direction of the slide easily a structure capable of opening and closing the damper in one actuator so not required useless force not friction is large in.

また、吹出し口が床面とほぼ垂直になるようにした気流吹出し部の中央に高圧空気発生部を備え、前記高圧空気発生部からの環形状に対して周方向の複数の連通部を介して前記気流吹出し部を保持し、前記高圧空気発生部を天井に取り付けたものであり、モータ等の重量物を含む高圧空気発生部を中心として、その外側に環状の吹出し部を備えることで、周方向の重量配分差が小さく水平設置に向いたバランスのよい構成とできるので、天井に取り付けて使用する涼をとるための送風機として適した構成にできる。 Further, air outlet comprises a high pressure air generator in the center of the blowing airflow portion to be substantially perpendicular to the floor surface, via a plurality of communication portions in the circumferential direction relative to the annular shape from the high pressure air generator holding the blowing airflow portion, wherein are those fitted with a high pressure air generator to the ceiling, around the high pressure air generator comprising a weight of the motor or the like, by providing the balloon portion of the annular outside, peripheral since it a good structure balanced weight distribution difference in the direction facing small horizontal installation, can the configuration suitable as a blower for taking cool to use attached to the ceiling.

また、高圧空気発生部が吹出し部の環形状外側にあり、ダンパが環形状に対して垂直方向にスライドするダンパであって、前記ダンパ面内の穴と連通部に通じる穴との重なり量を変えることで各吹出し部への風量を変更できるものであり、高圧空気発生部が吹出し部の外側にある場合は、環形状に対して周方向の一箇所で連通部を介して吹出し部を保持するのが望ましい。 Further, there is a ring shape outside of the high pressure air generator is blowing portion, the damper is a damper that slides in a direction perpendicular to the ring shape, the amount of overlap between the holes leading to the hole and communicating portion in the damper surface thing are those that can change the volume of air to each balloon unit for changing, when there outside of the high pressure air generator is blowing unit, holding the balloon portion through the communicating portion at one location in the circumferential direction with respect to the ring-shaped to is desirable. ここで、高圧空気発生部のためにダンパ前後の圧力差が大きいので、一辺がヒンジ等で固定された開閉式のダンパでは圧力によって開閉に余分な大きな力を要し、また連通部が一箇所であるために周方向にスライドするダンパでは周方向に無駄な可動範囲を確保しなければいけなくなり小型化の妨げとなるが、垂直方向のスライドにおいては不問となるので1つのアクチュエータで容易にダンパを開閉できる構造とできる。 Since a large pressure differential across the damper for the high pressure air generator, one side requires an extra large force to the opening and closing by the pressure at a fixed opening and closing dampers in the hinge or the like, also the communicating portion is one place the damper slides in the circumferential direction to be but hinders downsizing longer you must ensure useless movable range in the circumferential direction, readily damper one actuator since unquestioned in the vertical direction of the slide It can be a structure that can be opened and closed a.

また、吹出し口が床面と平行とした気流吹出し部の下方に高圧空気発生部を備え、前記高圧空気発生部下方に自立できるようスタンド部を備えたものであり、モータ等の重量物を含む高圧空気発生部を下方にして自立させることで、重心が下方にあるために安定して、床置きして使用する涼をとるための送風機として適した構成にできる。 It is intended air outlet comprises a high pressure air generator below the blowing airflow portion that is parallel to the floor, with a stand so that it can self to the high pressure air generator downwards, including the weight of the motor or the like be to self by the high pressure air generator downwards, can the configuration the center of gravity is stable because of the lower, suitable as a blower for taking cool be used in every floor.

次に、実施の形態2の動作を示す。 Next, an operation of the second embodiment.

操作者が前面の操作ボタン29でモータ5を駆動すると羽根車4が回転する。 Operator impeller 4 when driving the motor 5 at the front of the operation button 29 to rotate. 羽根車4は高圧発生に適したターボファンであり、回転の際の遠心力により吸込み口3の近辺の空気が吸い込まれて羽根車4の外側である高圧空気発生部6の内部に昇圧されて蓄えられる。 The impeller 4 is a turbofan suitable for high voltage generation, is boosted to the inside of the high pressure air generator 6 air near the suction port 3 by the centrifugal force is being in the outside of the impeller 4 sucked in during rotation It is stored. 蓄えられた空気はダンパによって前側連通部27と後側連通部28に気流を分けて昇圧送風する。 The stored air will boost blowing by dividing the air flow to the front communicating portion 27 and the rear side communication unit 28 by the damper. 前側連通部27へ分けられた空気は外形が300mmの円環状の外側気流吹出し部9の内部へ蓄えられて高圧状態となっているエネルギを利用して隙間1.5mmのスリットノズルである外側気流吹出し口14から内側30度へ向けて吹出される。 Outer airflow air divided to the front side communicating portion 27 is a slit nozzle gap 1.5mm utilizing the energy profile is stored into the interior of the outer blowing airflow portion 9 of the annular 300mm has a high pressure It is blown toward the blow-out port 14 to the inside 30 degrees. 後側連通部28へ分けられた空気は内側気流吹出し部8の内部へ蓄えられて高圧状態となっているエネルギを利用して隙間1.5mmのスリットノズルである内側気流吹出し口13から外側30度へ向けて吹出される。 The air is divided into the rear communication portion 28 is accumulated into the interior of the inner blowing airflow portion 8 outside 30 from the inner airflow blowing port 13 is a slit nozzle gap 1.5mm by using the energy which is the high pressure It is blown toward the degree.

ここで、内側気流吹出し口13と外側気流吹出し口14から同時に同風量で吹出されると、互いの気流が衝突して円環状の軸方向に吹出され、また内側気流吹出し口13のみの吹出しの場合には、内側30度方向のスポット送風となり、外側気流吹出し口14のみの吹出しの場合には、外側30度方向のワイド送風となり、と外側気流吹出し口14への風量のバランスで内側30度から真正面、真正面から外側30度の方向の気流が生成される。 Here, when blown by the airflow at the same time from the inside airflow blowing port 13 and the outer airflow blowing port 14, blown out in the axial direction of the annular mutual airflow collide, also the inner airflow blowing port 13 only balloon If becomes a spot blowing of inner 30 degree direction, when the outer air flow blowout port 14 only balloon becomes a wide blowing outside 30 degree direction, an inner 30 degrees balance air volume to the outside air flow blowout port 14 squarely, the direction of the air flow of the outside 30 ° squarely generated from. 風量バランスの調整はダンパ19で行われ、操作者からのコントロールにより小型モータ20が回転し、これに同期して歯車21が回転し、ダンパギヤ24に力が伝わることでダンパ19がスライドする。 Adjustment of the airflow balance is performed by the damper 19, a small motor 20 is rotated by the control from the operator, in synchronization with this rotation gear 21, the damper 19 is slid by the force is transmitted to Danpagiya 24. ダンパ19の回転による開口率の変化の例として、円環形状軸方向となる真正面方向送風のダンパ状態図を図13に示すように、前側穴30は前側連通部27と50%重なり、後側穴31は後側連通部28と50%重なり、高圧空気発生部6の内部で発生した気流が同量流れ込むようになり、全周で内側気流吹出し口13と外側気流吹出し口14から同時に同風量で吹出され互いの気流が衝突して図14に示す円環状の軸方向となる真正面向きに送風される。 Examples of a change in the aperture ratio due to the rotation of the damper 19, the damper state diagram of head-direction air blowing as the annular shape axis direction as shown in FIG. 13, the front hole 30 overlaps with 50% front communicating portion 27, the rear hole 31 overlaps 50% with rear communicating portion 28, airflow generated inside the high pressure air generator 6 is to flow the same amount, at the same time all around from the inner airflow blowing port 13 and the outer airflow blowout port 14 Dokazeryou in blown is mutual airflow collided is blown directly in front direction as the axial direction of the annular shown in FIG.

また、円環形状軸に対して30度外向き方向送風の状態図を図15に示すように、前側穴30は前側連通部27と100%重なって完全に開口しているが、後側穴31は後側連通部28の位置とずれているためにダンパ19でふさがれて、高圧空気発生部6の内部で発生した気流が前側連通部27のみに流れて図16に示す外向き方向の広範囲に送風される。 Further, as shown in FIG. 15 a state diagram of 30 Dogai orientation direction blown against annular shape axis, but the front hole 30 is fully opened overlaps 100% front communicating portion 27, the rear hole 31 because they are displaced from the position of the rear communication portion 28 is closed by the damper 19, the air flow generated inside of the high pressure air generator 6 is an outward direction shown in FIG. 16 flows only into the front communicating portion 27 It is widely blower. このようにダンパ19のスライド位置によって、前側連通部27を通る外側気流吹出し部9からの吹出し気流と後側連通部28を通る内側気流吹出し部8からの吹出し気流の量のバランスで前述のように内側30度から真正面、真正面から外側30度の方向の気流が生成され、これが操作者のコントロールで切替可能となっている。 Such slide position of the damper 19, an amount balance of the blowing airflow from the inner blowing airflow portion 8 through the air flow and a rear communicating portion 28 blowing from the outer blowing airflow portion 9 through the front communication unit 27 as described above squarely from the inside 30 degrees, the direction of the air flow of the outside 30 ° squarely is generated, and this is a switchable operator's control.

また、内側気流吹出し部8と外側気流吹出し部9が同心の円環形状であることで、円環部中心を軸として吹出し部が軸対称形状となるので、円環に対して周方向に一様な風を送ることができ、強風、弱風のムラの無い快適な気流を生成することができる。 Further, since the inner blowing airflow portion 8 and the outer airflow blowing unit 9 are concentric annular shape, because part balloon as an axis the annular portion center is axisymmetric, in the circumferential direction with respect to the circular one can be sent to such wind, strong wind, it is possible to generate a no comfortable stream of non-uniformity of the weak wind.

また、出し部の環形状の全周にわたって環形状に対して軸方向気流とした通常送風と、全周にわたって軸方向に対して内側に傾いた内向き気流としたスポット送風と、全周にわたって軸方向に対して外側に傾いた外向き気流としたワイド送風と、を切替可能としていることで、全周の気流を送風機真正面の内側に集中して強い涼風を受ける場合と、全周の気流を外側に向けて広範囲で涼風を受ける場合の選択が可能となり、状況に応じた気流を生成することが出来る。 Further, usually a blowing that axial air flow relative to the ring shape over the entire circumference of the out of the ring shape, and spot blast was inward airflow inclined inwardly relative to the axial direction over the entire circumference, the axis over the entire circumference by being a wide blast was outward airflow inclined outwardly, and can be switched to the direction, and if subjected to strong cool breeze to concentrate the entire circumference of the air flow inside the fan squarely, the entire circumference of the air flow must be unlocked when subjected to cool breeze in a wide range towards the outside, it is possible to generate an air flow according to the situation.

また、内側気流吹出し口13、外側気流吹出し口14への風量を高圧空気発生部6の内部の風量可変機構にて調整することで、1つのアクチュエータで容易にダンパを開閉できる構造とできる。 The inner airflow blowing port 13, the air volume of the outside air flow blowout port 14 by adjusting by the internal air volume varying mechanism of the high pressure air generator 6, it a structure that can easily open and close the damper at one actuator.

また、高圧空気発生部6が吹出し口7の環形状外側にあり、ダンパ19が環形状に対して垂直方向にスライドするダンパであって、ダンパ19面内の穴と連通部10に通じる穴との重なり量を変えることで各吹出し部への風量を変更できることで、高圧空気発生部が吹出し部の外側にある場合に1つのアクチュエータで容易にダンパを開閉できる構造とできる。 Further, there is a ring shape outside of the high pressure air generator 6 air outlet 7, a damper damper 19 slides in the direction perpendicular to the ring shape, and a hole leading to the hole and communicating portion 10 of the damper 19 in the plane by overlapping amount can change the volume of air to each balloon unit by changing a can easily be opened and closed the damper structure by a single actuator when outside of the high pressure air generator is blowing unit.
